〔水質計測処理〕
図３は、本発明の一実施形態である水質計測処理の流れを示すフローチャートである。図３に示すフローチャートは、端末装置４０から送信された水質計測処理の開始を要求するトリガ信号を水質計測管理装置２０が受信したタイミングで開始となり、水質計測処理はステップＳ１の処理に進む。 [Water quality measurement processing]
FIG. 3 is a flowchart showing a flow of water quality measurement processing according to an embodiment of the present invention. The flowchart shown in FIG. 3 starts at the timing when the water quality measurement management device 20 receives the trigger signal for requesting the start of the water quality measurement process transmitted from the terminal device 40, and the water quality measurement process proceeds to step S1.

ステップＳ１の処理では、計測ルート算出部２１が、計測地点データベース１０に格納されている計測地点マスタを参照して、水質を計測する複数の計測地点の最短ルートを算出する。そして、計測ルート算出部２１は、最短ルートの算出結果に基づいて情報送受信部２３を介して最初の計測地点の位置情報を端末装置４０に送信する。なお、計算ルート算出部２１は、端末装置４０の位置情報を取得し、取得した位置情報に基づいて最短ルートを算出するようにしてもよい。これにより、ステップＳ１の処理は完了し、水質計測処理はステップＳ２の処理に進む。   In the process of step S <b> 1, the measurement route calculation unit 21 refers to the measurement point master stored in the measurement point database 10 and calculates the shortest routes of a plurality of measurement points for measuring water quality. Then, the measurement route calculation unit 21 transmits the position information of the first measurement point to the terminal device 40 via the information transmission / reception unit 23 based on the calculation result of the shortest route. Note that the calculation route calculation unit 21 may acquire the position information of the terminal device 40 and calculate the shortest route based on the acquired position information. Thereby, the process of step S1 is completed and a water quality measurement process progresses to the process of step S2.

ステップＳ２の処理では、情報送受信部４１が、水質計測管理装置２０から送信された計測地点の位置情報を受信する。また、位置情報取得部４２が、例えばＧＰＳ衛生からの信号を受信することによって端末装置４０の位置情報を取得する。そして、出力部４３が、計測地点の位置情報と端末装置４０の位置情報とを比較することによって、計測地点の方角と計測地点までの距離に関する情報を出力する。オペレータは、出力部４３が出力した情報に基づいて計測地点へと移動する。これにより、ステップＳ２の処理は完了し、水質計測処理はステップＳ３の処理に進む。   In the process of step S <b> 2, the information transmitting / receiving unit 41 receives the position information of the measurement point transmitted from the water quality measurement management device 20. Moreover, the position information acquisition part 42 acquires the position information of the terminal device 40 by receiving the signal from GPS hygiene, for example. And the output part 43 outputs the information regarding the direction to the direction of a measurement point, and the distance to a measurement point by comparing the positional information on a measurement point, and the positional information on the terminal device 40. FIG. The operator moves to the measurement point based on the information output by the output unit 43. Thereby, the process of step S2 is completed and a water quality measurement process progresses to the process of step S3.

ステップＳ３の処理では、情報送受信部４１が、位置情報取得部４２を介して端末装置４０の位置情報を定期的に取得し、取得した端末装置４０の位置情報を水質計測管理装置２０に送信する。これにより、ステップＳ３の処理は完了し、水質計測処理はステップＳ４の処理に進む。   In the process of step S <b> 3, the information transmission / reception unit 41 periodically acquires the position information of the terminal device 40 via the position information acquisition unit 42 and transmits the acquired position information of the terminal device 40 to the water quality measurement management device 20. . Thereby, the process of step S3 is completed and a water quality measurement process progresses to the process of step S4.

ステップＳ４の処理では、計測作業制御部２２が、端末装置４０から送信された端末装置４０の位置情報に基づいてオペレータが計測地点に到着したか否かを判別する。そして、計測作業制御部２２は、オペレータが計測地点に到着したと判別されたタイミングで情報送受信部２３を介して水質の計測作業の開始を指示する計測指示信号を端末装置４０に送信する。これにより、ステップＳ４の処理は完了し、水質計測処理はステップＳ５の処理に進む。   In the process of step S <b> 4, the measurement work control unit 22 determines whether the operator has arrived at the measurement point based on the position information of the terminal device 40 transmitted from the terminal device 40. And the measurement work control part 22 transmits the measurement instruction | indication signal which instruct | indicates the start of the measurement work of water quality to the terminal device 40 via the information transmission / reception part 23 at the timing determined that the operator arrived at the measurement point. Thereby, the process of step S4 is completed and a water quality measurement process progresses to the process of step S5.

ステップＳ５の処理では、出力部４３が、水質計測管理装置２０から送信された計測指示信号を情報送受信部４１が受信するのに応じて、水質の計測作業の開始を指示する情報を出力する。オペレータは、出力部４３が出力した情報に基づいて、水質計測装置３０を利用して計測地点の水質を計測する。これにより、ステップＳ５の処理は完了し、水質計測処理はステップＳ６の処理に進む。   In the process of step S <b> 5, the output unit 43 outputs information instructing the start of water quality measurement work in response to the information transmission / reception unit 41 receiving the measurement instruction signal transmitted from the water quality measurement management device 20. The operator measures the water quality at the measurement point using the water quality measuring device 30 based on the information output by the output unit 43. Thereby, the process of step S5 is completed and a water quality measurement process progresses to the process of step S6.

ステップＳ６の処理では、水質計測装置２０が、計測された水質のデータを端末装置４０に出力し、情報送受信部４１が、水質計測装置２０が出力した水質のデータを水質計測管理装置２０に送信する。これにより、ステップＳ６の処理は完了し、水質計測処理はステップＳ７の処理に進む。   In the process of step S <b> 6, the water quality measurement device 20 outputs the measured water quality data to the terminal device 40, and the information transmission / reception unit 41 transmits the water quality data output from the water quality measurement device 20 to the water quality measurement management device 20. To do. Thereby, the process of step S6 is completed and a water quality measurement process progresses to the process of step S7.

ステップＳ７の処理では、計測作業制御部２２が、情報送受信部２３を介して端末装置４０から送信された水質のデータを受信することによって、水質の計測作業が完了したことを確認する。これにより、ステップＳ７の処理は完了し、水質計測処理はステップＳ８の処理に進む。   In the process of step S <b> 7, the measurement work control unit 22 receives the water quality data transmitted from the terminal device 40 via the information transmission / reception unit 23, thereby confirming that the water quality measurement work has been completed. Thereby, the process of step S7 is completed and a water quality measurement process progresses to the process of step S8.

ステップＳ８の処理では、計測作業制御部２２が、受信した水質データを計測地点マスタに記述されている標準計測値と比較することによって計測値が正常であるか否かを判別する。判別の結果、計測値が正常である場合、計測作業制御部２２は、ステップＳ１の処理によって算出された最短計測ルートに基づいて水質の計測作業を進めるように水質計測処理をステップＳ２の処理に戻す。一方、計測値が異常である場合には、計測作業制御部２２は、水質計測処理をステップＳ９の処理に進める。   In the process of step S8, the measurement work control unit 22 determines whether or not the measurement value is normal by comparing the received water quality data with the standard measurement value described in the measurement point master. If the measurement value is normal as a result of the determination, the measurement work control unit 22 changes the water quality measurement process to the process of step S2 so as to advance the water quality measurement work based on the shortest measurement route calculated by the process of step S1. return. On the other hand, when the measurement value is abnormal, the measurement work control unit 22 advances the water quality measurement process to the process of step S9.

ステップＳ９の処理では、計測作業制御部２２が、水質異常が発生している地点を特定するために、計測地点より上流側の地点を次の計測地点にするように次の計測地点を変更する。具体的には、図４に示すように、河川が直線Ｌに示すように高度Ｈ２から高度Ｈ１に向かって流れている場合において、最下流側の計測地点Ｐ１における計測値が異常である場合、始めに、計測作業制御部２２は、計測地点Ｐ１に隣接する上流側の計測地点Ｐ２を飛ばして、計測地点Ｐ１より２地点上流側にある計測地点Ｐ３を次の計測地点とし、計測地点Ｐ３の水質を計測するように水質計測処理をステップＳ２の処理に戻す。   In the process of step S9, the measurement work control unit 22 changes the next measurement point so that the point upstream of the measurement point becomes the next measurement point in order to identify the point where the water quality abnormality has occurred. . Specifically, as shown in FIG. 4, when the river flows from the altitude H2 toward the altitude H1 as indicated by the straight line L, the measurement value at the measurement point P1 on the most downstream side is abnormal. First, the measurement work control unit 22 skips the upstream measurement point P2 adjacent to the measurement point P1, sets the measurement point P3 two points upstream from the measurement point P1 as the next measurement point, and sets the measurement point P3. The water quality measurement process is returned to the process of step S2 so as to measure the water quality.

次に、計測作業制御部２２は、計測地点Ｐ３における水質計測処理の結果、計測地点Ｐ３の計測値が異常である場合、同様にして、計測地点Ｐ３より２地点上流側にある計測地点Ｐ５を次の計測地点とし、計測地点Ｐ５の水質を計測するように水質計測処理をステップＳ２の処理に戻す。そして、計測地点Ｐ５（又は計測地点Ｐ３）の計測値が正常である場合には、計測作業制御部２２は、計測地点Ｐ５（又は計測地点Ｐ３）に隣接する下流側の計測地点Ｐ４（又は計測地点Ｐ２）を次の計測地点とし、計測地点Ｐ４（又は計測地点Ｐ２）の水質を計測するように水質計測処理をステップＳ２の処理に戻す。   Next, when the measurement value at the measurement point P3 is abnormal as a result of the water quality measurement process at the measurement point P3, the measurement work control unit 22 similarly sets the measurement point P5 that is two points upstream from the measurement point P3. As a next measurement point, the water quality measurement process is returned to the process of step S2 so as to measure the water quality at the measurement point P5. When the measurement value at the measurement point P5 (or measurement point P3) is normal, the measurement work control unit 22 measures the downstream measurement point P4 (or measurement) adjacent to the measurement point P5 (or measurement point P3). The point P2) is set as the next measurement point, and the water quality measurement process is returned to the process of step S2 so as to measure the water quality at the measurement point P4 (or measurement point P2).

このように、このステップＳ９の処理では、計測作業制御部２２は、水質異常が発生した際、水が上流側から下流側に流れるという特性を利用して、水質の計測地点をより上流側の計測地点に順次変更する。この処理により、水質の悪化が生じている地点を特定することができる。なお、本実施形態では、計測作業制御部２２は、水質を測定した計測地点から２地点上流側にある計測地点を次の計測地点とする、換言すれば、１地点飛ばしで次の計測地点を決定したが、飛ばす計測地点の数は１に限定されることはなく、任意に設定することができる。これにより、ステップＳ９の処理は完了し、水質計測処理はステップＳ２の処理に戻る。   Thus, in the process of step S9, the measurement work control unit 22 uses the characteristic that when the water quality abnormality occurs, the water flows from the upstream side to the downstream side, the water quality measurement point is set further upstream. Change to measurement points sequentially. By this processing, it is possible to identify a point where water quality is deteriorated. In the present embodiment, the measurement work control unit 22 sets the measurement point that is two points upstream from the measurement point where the water quality is measured as the next measurement point. In other words, the next measurement point is skipped by one point. Although determined, the number of measurement points to be skipped is not limited to 1 and can be arbitrarily set. Thereby, the process of step S9 is completed and the water quality measurement process returns to the process of step S2.

以上の説明から明らかなように、本発明の一実施形態である水質計測処理では、水質計測管理装置２０が、水質を計測する計測地点の位置情報を端末装置４０に送信する。端末装置４０は、電気通信回線５０を介して水質計測管理装置２０から送信された計測地点の位置情報を受信し、電気通信回線５０を介して水質計測装置３０によって計測された計測地点の水質のデータを水質計測管理装置２０に送信する。そして、水質計測管理装置２０は、電気通信回線５０を介して端末装置４０から送信された計測地点の水質のデータを受信する。このような構成によれば、計測地点毎に計測装置を設置することなく任意の計測地点における水質のデータを計測できるので、水道水源の水質を安価に計測することができる。   As is clear from the above description, in the water quality measurement process that is one embodiment of the present invention, the water quality measurement management device 20 transmits the position information of the measurement point for measuring the water quality to the terminal device 40. The terminal device 40 receives the position information of the measurement point transmitted from the water quality measurement management device 20 via the telecommunication line 50, and the water quality of the measurement point measured by the water quality measurement device 30 via the telecommunication line 50. Data is transmitted to the water quality measurement management device 20. And the water quality measurement management apparatus 20 receives the water quality data of the measurement point transmitted from the terminal device 40 via the electric communication line 50. According to such a configuration, water quality data at an arbitrary measurement point can be measured without installing a measurement device for each measurement point, so that the water quality of the tap water source can be measured at a low cost.

以上、本発明者によってなされた発明を適用した実施の形態について説明したが、本実施形態による本発明の開示の一部をなす記述および図面により本発明は限定されることはない。すなわち、本実施形態に基づいて当業者などによりなされる他の実施の形態、実施例および運用技術などは全て本発明の範疇に含まれる。   Although the embodiment to which the invention made by the present inventor is applied has been described above, the present invention is not limited by the description and the drawings that form a part of the disclosure of the present invention according to this embodiment.
